Low rise sway frames

摘要

It was refreshing going over the Park and Wang paper dwelling on low-rise semi-rigid steel frames. The conclusion bears on the feasibility of adopting such unbraced frames as the sway frame deflection may be controlled to within SLS limits. The above principle may be further shifted onto precast medium rise large panel structures as may be utilised in warehousing. Here large clear spans are dictated by maneuvering requirements; bracing elements may be absent due to deep plan forms. The intermediate floor slabs may be considered to be pin-jointed to the wall panel structures, whilst tying detail requirements may achieve some form of stability with respect to robustness. However, essentially the floor slabs are considered as props.
